Relation-theoretic metrical coincidence and common fixed point theorems under nonlinear contractions
Relation-theoretic metrical coincidence and common fixed point theorems under nonlinear contractions
In this paper, we prove coincidence and common fixed points results under nonlinear contractions on a metric space equipped with an arbitrary binary relation. Our results extend, generalize, modify and unify several known results especially those are contained in Berzig [J. Fixed Point Theory Appl. 12, 221-238 (2012))] and Alam …
